Here's a betting spar.

Change the "this.boxName" to 1 or 2 [Only two per level, could add more on slight modifications]. Add two of these in the level.

function onCreated() {
  this.setShape(1, 32, 32);
  this.boxName = 1;
}

//Function called to pick up an item
function onActionFound(id) {
  if (level.("objectOwner" @ this.boxName) != null) {
    return false;
  }
  for (temp.i: findnearestnpcs(this.x - 2, this.y - 2, 4, 4) {
    if (temp.i.itemid == temp.id) {

      level.("objectOwner" @ this.boxName) = player; 
      level.("objectItem1" @ this.boxName) = {temp.i.mudid, temp.i.mudquantity};
      temp.i.destroy();
      return;
    }
  }
}

Here's the main control, on the GK system this will probably need ajusting more than anything

function onCreated() {
  this.setShape(1, 32, 32);
  this.boxModes = {1, 2};
  level.deathAction = {this.x, this.y};
  //Maybe there's a public function for when a person dies in a level! 
  //If not, I could add a timeout, just better to send an action once someone dies
}

//If there is, here's how it'd work
function onActionDeathAction(accountName) {
  for (temp.i: this.boxModes) {
    temp.ownerAccounts.add(level.("objectOwner" @ temp.i).account); 
    temp.itemDetails.add(level.("objectItem1" @ temp.i));
  }
  if (temp.ownerAccounts == null) {
    return false;
  }
  if (temp.accountName in temp.ownerAccounts) {
    temp.winner = temp.ownerAccounts.remove(temp.accountName);
    temp.winner.chat = "You've won the bet by slain thy opponent!";
    for (temp.i: temp.itemDetails) {
     //addinvobject(int, int) - I assue id/quantity
      temp.winner.addinvobject(temp.i[0], temp.i[1]);
    }
    level.objectOwner1 = null;
    level.objectOwner2 = null;
  }
}
